:stop 7 or ,on the "fixed stop 8. The ing very rapid, the sfameis usedto obtztin it two sto is- 7 and 8 are integral with sudden operation ofthe Starting switch for; the .chassis. A suitable spring 9' fixed theelectric motor. Similarly, an oscillatory rection, can be utilized forsupplying current to this motor.

Briefly the operation is limited to bringing the arm .6 to bear on thestop 7 by any suitable means; the effect of this movement is to causethe gear wheels 2 and 3 to mesh and at the'saine time to supply currentto the electric motor and once the engine is started the disengagementof the gear wheels 2-and 3 and the cutting oil of the current areeffected automatically by the simple rocking movement of the arm 3toward the stop 8.

It is obvious that instead of the gear wheels 2 and 3 friction rollersor any other connecting means may be employed.

Having now particularly, described .and

ascertained the nature of my said invention and in what manner the sameis to be performed, I declare that what I claim is 1- 1.. Thecombination with a rotary'part of an internal combustion engine, of anelecupon which ,said motor is ivotally mounted to swing into and out ofoperative position with respect to said rotary part of the en'-.

a pair of stops against one of which said arm abuts in either positionof themotor, a spring acting on said arm and secured at a fixed pointbetween said stops andbelow the axis of oscillation of said arm wherebysaid spring tends to yieldingly retain the motor ineither ofitspositions, an electric switch cont-rolled by themovement of said arm.and an electric circuit in which said motor is connected, saidcircuitbeinguclosed by said switch when the motor moves to its op.-erative position and-openedj'by said switch when the motor movest'o-its' inoperative position. 4 In testimony whereof I afiix' mysignature, inpr'esence oftwo witnesses.
